Triplocania altamira n. sp.

( Figs 1–12 )

Diagnosis. Belonging in Subgroup MPB2A (see Classification below). (Hypandrium of three sclerites, one central, flanked by smaller lateral sclerites). It is related to species group andaqui (see Discussion below), but constitutes a species group of its own, diagnosed as follows: central sclerite of hypandrium rounded anteriorly; posterolateral corners extended posteriorly to form two medium sized processes narrowing distally, and two median, long acuminate processes, leaving a wide, U-shaped concavity between them. Mesal endophallic sclerites large, fused, bearing a strongly sclerotized acuminate process on the posterior border. Lateral endophallic sclerites bow-shaped. IX sternum with widened anterior area, angled and rounded edges, with anterior side convex and two posterior lobes.

Male. Color (in 80% ethanol). Body pale brown. Head pale brown, with pattern of small dark brown spots ( Fig. 3 ). Compound eyes dark brown, ocelli hyaline, with ochre centripetal crescents; scape, pedicel and f1 pale brown, f2 pale brown, f5–f11 dark brown, all flagellomeres cream apically; maxillary palps pale brown, Mx4 dark brown. Thorax pale brown, with small ochre and cream spots. Tergal lobes of meso- and metathorax brown, with ochre spots. Thoracic mesopleura pale brown, with small ochre spots. Coxae, trochanters and femora cream; tibiae and tarsi 1 pale brown; tarsomeres 2–3 pale brown. Forewings with pale brown spots at the ends of veins R, M and CuA 1; pterostigma pale brown, with large dark brown spot, a pale brown area almost triangular along CuA to end of A1; a pale brown band along CuA 1; veins brown, with brown areolae at setal insertions and with dark brown spots at wing margin ( Fig. 1 ). Hindwings mostly hyaline, veins brown, with brown spots at extreme of veins R and M ( Fig. 2 ). Abdomen cream with ochre spots. Epiproct and paraprocts cream. Sclerites of hypandrium light brown to cream, median processes darker than the lateral processes. Endophallic sclerites dark brown.

Morphology. As in diagnosis, plus the following: Head ( Fig. 3 ): H/MxW: 1.48; H/D: 2.16; IO/MxW: 0.74. Vertex slightly emarginate, almost at the same level as the upper margin of the compound eyes. Outer cusp of lacinial tips broad, with five wide denticles. Mx4/Mx2: 1.19. Forewings ( Fig. 1 ): L/W: 2.63. Pterostigma elongate: lp/wp: 4.94. Areola postica triangular: la/ha: 1.88, CuA 1 gently concave distally, almost straight. Hindwings ( Fig. 2 ): l/p: 2.98. Hypandrium of three sclerites ( Fig. 5 ). Phallosome ( Fig. 6 ); side struts Y-shaped, with short stem. External parameres round distally, with pores. Paraprocts oval, with abundant medium sized setae and some macrosetae on apical third, with at least two macrosetae distally spatulate; sensory fields with 32 trichobothria on basal rosettes ( Fig. 4 ). Epiproct ( Fig. 4 ) wide, convex anteriorly, broadly rounded posteriorly, with abundant microsetae and setae as illustrated.

Female. Color. As in the male. Subgenital plate pale brown, with pigmented area dark brown. IX sternum brown, with dark brown spots; gonapophyses brown to light brown, with longitudinal area dark brown.

Morphology. Head ( Fig. 9 ): H/MxW: 1.45, H/D: 2.47; compound eyes large, IO/MxW: 0.84. Vertex as in the male. Outer cusp of lacinial tips broad, with seven denticles. Mx4/Mx2: 1.27. Forewings ( Fig. 7 ) as in the male, L/W: 2.64, pterostigma: lp/wp: 4.66; areola postica, al/ah: 1.98. Hindwings ( Fig. 8 ): l/w: 2.93. Subgenital plate ( Fig. 11 ) broad, setose, triangular. Gonapophyses ( Fig. 12 ): v1 slender, elongate, acuminate; v2+3: v2 with 5 macrosetae, distal process sinuous, acuminate, with field of microspines. Paraprocts ( Fig. 10 ) broadly triangular, with abundant median sized setae and some macrosetae, one of them with spatulate apex as illustrated; sensory fields with 30 trichobothria on basal rosettes. Epiproct ( Fig. 10 ) triangular, rounded posteriorly, three macrosetae mesally, other macrosetae on sides and on posterior margin, medium to short sized setae along sides and apex, as illustrated.
